Communication Models for Parallel Computer
Architectures
•Two distinct models have been proposed for how
CPUs in a parallel computer system should
communicate.
–In the first model, all CPUs share a common physical
memory.
•This kind of system is called a multiprocessor or shared memory
system.
–In the second design, each CPU has its own private
memory.
•Such a design is called a multicomputer or distributed memory
system.
